PATENT OFFI Ea PLUMB, RULE, AND LEVEL.

SPECIFICATION forming part of Letters Patent No. 732,614, dated J une30, 1903.

application filed March 9, 1903.

To aZZ whom it may concern:

Be it known that I, AARON THOMAS BIN- KERD, a citizen of the UnitedStates, residing at Allegheny, in the county of Allegheny and State ofPennsylvania, have inventedcertain new and useful Improvements inPlumbs, Rules, and Levels;"and I do declare the following to be a full,clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame.

Myinvention relates to certain new and useful improvements in plumbs,rules, and spirit levels; and its object is to provide a device of thischaracter which is simple in construction, durable in use, andcomparatively inexpensive to manufacture.

A further object is to provide an adjustable spirit-level which may beeasily and quickly applied to and detached from the stock.

With these and other objects in View the invention consists of certainnovel features of construction, combination, and arrangement of parts,as will be hereinafter more fully described, and particularly pointedout in the appended claims.

In the drawings, Figure 1 is a front eleva-' tion of, my improved plumb,rule, and spirit level. Fig. 2 is an enlarged front elevation of one ofthe spirit-levels. Figs. 3 and 4 are sectional views through the same,taken on the lines 3 3 and 4 4 of Fig. 2. V

Referringmore particularly to the drawings, the numeral 1 denotes thestock or body of the device,which is provided with the opening 2,adjacent to its upper end, and'with a similar opening 3 at its center.These openings are adapted to contain my adjustable spiritlevels and areformed with countersunk ends 4:, upon which the adjustable plates 5 arepivoted by the screws 6. Each of these plates is formed with anelongated aperture or slot 7, through which a screw 8 passes in order tobind the plate upon the countersunk portion 4 of the opening, and thushold the plate in an adjusted position.

The spirit vials or bulbs 9 are cemented or otherwise secured in theholders 10, each of which is constructed of a rectangular blank having aportion curved upon itself to form a tubular socket 11 to receive thevial or bulb. The straight portion of the holder forms a Serial No.146,962. (No model.)

base, which is pivoted to the plate 5 by the screw 12 and is madeadjustable upon said plate 5 by providing it with the elongated apertureor slot 13, through which the'screw '14is adapted to pass to clamp thebase of the holder upon the plate.

It will be observed that the pivots of the plates 5 and the bases of thevial-holders 10 are upon opposite ends of the plates, thereby permittingof a very quick and simple adjustment of the vial by the loosening ofone or the other of the screws 8 and 14, as may be necessary to elevateor depress-either end of 7 stock and that the same may be quicklyapplied to and adjusted upon any piece of lumber or other material witha straight edge, thereby forming a very inexpensive plumb, rule, andlevel. q From the foregoing description, taken in connection with theaccompanying drawings, the construction and operation of the inventionwill be readily understood without requiring a more extendedexplanation.

Various changes in the form, proportion, and the minor details ofconstruction may be resorted to without departing from the principle orsacrificing any of the advantages of this invention.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is- Y 1. The combination of a stock, a platepivoted at one end to said stockand formed at its opposite end with anapertu're,a clamp ing-screw in said aperture for adjusting said plateupon the stock, a vial, a holder therefor having a base pivoted at oneend to the free or adjustable end of the said plate and provided with anaperture atitsopposite end, and a clamping-screwin said aperture foradjusting said base upon the plate, substantially as described.

2. The combination of a stock, a rectangular plate pivoted at one end tosaid stock and formed at its opposite end with an aperture, a clamping-screw in said aperture for adjustingsaid plate upon the stock, avial, a holder formed with a tubular portion to receive said vial andwith a straight portion or base, said base being pivoted at one end tothe free or adjustable end of the said plate, and being provided with anaperture at its opposite end, and a clamping-screw in said aperture foradjusting said base upon the plate, substantially as described.

In testimony whereof I have hereunto set my hand in presence of twosubscribing witnesses.

AARON THOMAS BINKERD.
